Publication number: 20170165492Abstract: An improved architecture for an implantable medical device using a primary battery is disclosed which reduces the circumstances in which the voltage of the primary battery is boosted, and hence reduces the power draw in the implant. The architecture includes a boost converter for selectively boosting the voltage of the primary battery and for supplying that boosted voltage to certain of the circuit blocks, including digital circuitry, analog circuitry, and memory. However, the boost converter is only used to boost the battery voltage when its magnitude is below a threshold; if above the threshold, the battery voltage is passed to the circuit blocks without boosting. Additionally, some circuitry capable of operation even at low battery voltages—including the telemetry tank circuitry and the compliance voltage generator—receives the battery voltage directly without boosting, and without regard to the current magnitude of the battery voltage.Type: ApplicationFiled: February 13, 2017Publication date: June 15, 2017Inventors: Robert G. Lamont, Jordi Parramon

Publication number: 20170165493Abstract: The present disclosure provides systems and methods for assembling a subassembly for use in manufacturing an implantable device header. A method includes placing a first split web into a top platen, placing a second split web into a bottom platen, placing a conductor assembly and an antenna assembly in the bottom platen on top of the second split web, compressing the top and bottom platens together, heating the top and bottom platens until a predetermined temperature and a predetermined pressure are reached, such that first split web is fused to the second split web to form the subassembly, separating the top and bottom platens, and removing the formed subassembly.Type: ApplicationFiled: December 15, 2015Publication date: June 15, 2017Inventors: Dino Bortolin, Ofer Rosenzweig

Publication number: 20170165495Abstract: Disclosed are systems, devices and methods that produce at least two distinct temporal components from two distinct endocardial electrogram (EGM) signals collected concurrently, determines a non-temporal 2D characteristic representative of the cardiac cycle to be analyzed, from the variations of one of the temporal components as a function of another of the temporal components and comparing the characteristic of the current cycle to two reference characteristics previously obtained and stored, one in a situation of complete capture and the other in a situation of spontaneous rhythm. Respective values of similarity descriptors are derived of these two comparisons, which are used to calculate a metric quantifying a fusion rate.Type: ApplicationFiled: November 4, 2016Publication date: June 15, 2017Inventors: Paola Milpied, Delphine Feuerstein
